Abstract (en)
[origin: EP0242439A2] The wideband amplifier includes an active equivalent RC network (Q5, Q6) connected across the emitters of a differential amplifier (Q1-Q4). The active RC network (Q5,Q6) exploits inherent junction capacitance and resistance, and is controlled in such a manner that the desired compensation value is provided.
